Researches at the Imperial College in London have developed a reusable fabric that can be taken off and re-worn:

The spray consists of short fibres that are mixed into a solvent, allowing it to be sprayed from a can or high-pressure spray gun. The fibres are mixed with polymers that bind them together to form a fabric. The texture of the fabric can be varied by using wool, linen or acrylic fibres.

The fabric, which dries when it meets the skin, is very cold when it is sprayed on, a limitation that may frustrate hopes for spray-on trousers and other garments.

The researchers hope that the technology can be adapted to create spray-on bandages, among other applications. You can view a video of the creation process at the link.

Eric Nylund wrote a couple of SF novels, "Signal to Noise" & "A Signal Shattered", that featured spray-on spacesuits.This was my only gripe with an otherwise awesome pair of books, because an individual was supposedly able to apply it to themselves out of a can, apparently over their clothes, with a solvent spray for removal afterwards.What about their back? What about overspray? What about... ?Too many problems with that idea, so I just had to let it go in order to enjoy the rest of the story.

Wow i guess i unknowingly have been testing the prototypes of this amazing tech. as long as i can remember my clothes have been reusable and i evenbeen so lucky that i got the models that can be taken off.The spray on part is new though, problem is i scratch my balls alot, my question being does it ruin the elastics?
